SEC. 9-1. TITLE

This Chapter may be known and cited as the "Subdivision Ordinance" of Scott County, Iowa.

SEC. 9-2. PURPOSE

A. To provide for accurate, clear, and concise legal descriptions of real estate in order to prevent, wherever possible, land boundary disputes or real estate title problems.

B. To encourage orderly development in unincorporated Scott County and

provide for the regulation and control of the extension of public and private improvements and public services; to facilitate the adequate provision of transportation, water, sewerage, schools, parks, and other public requirements; to provide for the improvement of land, and the design of subdivisions, consistent with the goals and policies set forth in the Scott County Development Plan.

C. To provide for a balance between the land use rights of individual landowners

and the economic, social, and environmental concerns of the public when Scott County is reviewing proposed development, or enforcing land use regulations that will enable Scott County to encourage efficient, yet attractive, urban development patterns; to provide for the residential and business needs of the County through new and replatted subdivisions; to preserve the availability of agricultural land; to protect soil from wind and water erosion; and to protect environmentally sensitive areas from degradation.

D. To ensure that all subdivisions of land in unincorporated Scott County are

reviewed in a consistent manner and to ensure that divisions of land do not escape review simply because they occur one division at a time or are performed to accord with legal proceedings, orders or testamentary dispositions.

SEC. 9-3. GENERAL JURISDICTION

Scott County hereby implements the authority granted counties to regulate the division of land as authorized by Chapter 409A, Code of Iowa. It shall be unlawful for any person who has equitable or legal title to or any executor or administrator exercising possession or control over real estate located in unincorporated Scott County to divide the parcel of real estate into two or more smaller parcels or lots unless by a plat in accordance with this Chapter. The plat shall be submitted to the Scott County Board of Supervisors or its designee for approval or disapproval.



No plat shall be recorded, no lots sold, and no land dedicated to the County unless and until approved as herein provided.

SEC. 9-4 INTERPRETATION, CONFLICT AND SEVERABILITY

A. In their interpretation and application, the provisions of this ordinance shall be held to be uniformly applicable minimum requirements. More stringent provisions may be required if it is demonstrated that different standards are necessary to promote the public health, safety and welfare.

B. Where this Chapter conflicts with another law or administrative rule of the

State or Federal Government, the provision of the ordinance, law, or rule with the greater restrictive impact shall apply. The subdivider and property owner shall divide their real estate in compliance with the stricter standard that affects their property.

Where this Chapter differs with private easements, covenants, or restrictive agreements, the more restrictive standard shall govern. If such private property restrictions impose lesser requirements on the subdivision or division of land, the provisions of this Chapter, or applicable State and/or Federal law, shall control.

C. The provisions of this ordinance are separable. If a section, sentence, clause,

or phrase of this ordinance is adjudged by a court of competent jurisdiction to be invalid, the decision shall not affect the remaining portions of this ordinance.

G. Status of Approval: Approval by the Board of Supervisors authorizes the filing

of the Final Plat with the County Auditor and Recorder, in accordance with the provisions of existing statutes and following procedures as required by the Auditor and Recorder, and acknowledges the acceptance of all roads, streets,



alleys, easements, parks or other areas reserved for or dedicated to the public along with the required surety bonds or checks guaranteeing that the improvements required herein shall be installed.

H. Duration of Approval: Approval of the Final Plat may become null and void if

the plat is not recorded within sixty (60) days of Board of Supervisors approval. After said period of sixty (60) days, the Director shall place on the agenda of the Commission the Final Plat to consider whether it should be nullified or granted an extension. The subdivider shall be notified of the hearing and provided time to explain why the Final Plat was not recorded within sixty (60) days. After a hearing, the Commission shall recommend to the Board of Supervisors to either nullify or extend the recording time for the Final Plat. The Board shall review the recommendation and act to either nullify or grant an extension.

I. Appeal of disapproval: If the plat is disapproved or approved subject to condition(s) by the Board of Supervisors, the applicant has the right to appeal, subject to the provisions of 409A.10, Code of Iowa, to the District Court within twenty (20) days after the date of the denial of the application or the date of the receipt by the applicant of the requirements for approval of the subdivision.

No Minor or Preliminary Plat shall be approved by either the Planning and Zoning Commission or the Board of Supervisors unless it conforms to the Scott County Development Plan, the Land Use Policies, and the Scott County Zoning Ordinance. Such plats shall also conform to the following minimum standards and requirements:

A. Large Lot Subdivision: Whenever the area is divided into lots of such size that

there are indications that the lot will eventually be re-subdivided into small building lots, consideration shall be given to the street and lot arrangement of the original subdivision so that additional minor streets can be opened which will permit a logical arrangement of small lots.

B. Relation to Adjoining Street System: The arrangement of streets in new

subdivisions shall make provision for the continuation of the principal existing streets in adjoining subdivisions, or for a proper intersection with said streets in the new subdivision shall connect therewith, or their proper projection where adjoining property is not subdivided insofar as they may be necessary for public requirements. The width of such streets in new subdivisions shall not be less than the minimum street widths established herein. The street arrangement shall also be such as to cause no hardship to owners of adjoining property when they plat their own land and seek to provide for convenient



access to it.

The platting of half streets shall not be permitted.

C. Street: (See Appendix I).

(1) The width of the traffic surface for major thoroughfares shall conform to the widths designated by the Board of Supervisors upon recommendation of the County Engineer.

(2) The minimum right-of-way for local residential streets shall be fifty (50)

feet, but may be wider due to estimated traffic and terrain (see Appendix I for specific R.O.W. requirements).

(3) Subdivisions with only one access shall not contain over thirty (30)

residential lots unless streets within such subdivision are extended to the boundary of adjoining undeveloped property to allow for future connection and additional access; in which case such subdivision shall not contain more than fifty (50) residential lots until such time as a second access is provided. Cul-de-sacs or dead-end streets designed to be permanently closed shall not be more than thirteen hundred twenty feet (1,320') in length, when measured from centerline of the nearest intersecting street and the center radius of cul-de-sac turn around. All dead-end streets shall terminate in a circular right-of-way or cul-de-sac with a minimum easement or right of way diameter of one hundred (100) feet or other equally suitable provision for vehicular turning space. When a street is to be terminated at the boundary of the subdivision temporarily, until adjacent land is to be subdivided, a temporary circular right-of-way or cul-de-sac shall be provided. The surfacing required for such a temporary circular right-of-way or cul-de-sac shall be established by the County Engineer.

(4) It shall be the responsibility of the Board of Supervisors upon recommendation of the Planning and Zoning Commission to assign street names to new roads in Scott County as follows:

a. The developer may propose street names or numbers to the

Commission. The official street designation shall comply with the standards of Section 8-4. County Code. The final plat shall show the assigned street name or number prior to recording. The residence or business address will not be assigned until a building permit is issued.



b. All new subdivisions shall be required to comply with the Rural Address System as adopted in Chapter 8 of the County Code.

c. Subdivision property owners on private roads and streets are

responsible for the purchase, installation, and maintenance of road identification markers at private subdivision road intersections within their subdivision. The specifications for the markers shall be in accordance with the National Manual of Uniform Traffic Control Devices as specified in Section 8-2(6) and Section 8-7 of the County Code. Only those names/numbers assigned in the Property Numbering Map(s) are allowed on private roadway intersections. Any other roadway designations are in violation of this Chapter and must be removed within a reasonable time period.

(5) The intersection angle of road center lines shall be between eighty (80)

and one hundred (100) degrees.

(6) Road intersections with center line offsets of less than one hundred fifty (150) feet shall be prohibited.

(7) Intersections of more than two (2) roads at a point shall be prohibited.

(8) Streets and roadways will be built to specifications as approved by the

Board of Supervisors (see SEC. 9-19 and Appendix I). Roads to be dedicated to the county will meet the specifications and standards of the Board of Supervisors and the County Engineer. Private streets are permitted and must meet the standards as described in SEC. 9-19.

(9) Proper access shall be given to all lots from a dedicated or private street.

The Policy and Regulations for Entrances to Primary Roads of the Iowa Department of Transportation are herewith adopted by reference and made a part of this Chapter, and violation of the aforesaid Policy and Regulations is a violation of this Chapter and subject to the penalties contained herein with the same force and effect as if said Policy and Regulations were contained herein. Said Policy and Regulations are on file in the Office of the County Engineer.

(10) Access from lots to county and state roads shall be made via subdivision

roads whenever possible. (11) The subdivider's engineer shall certify that the sight distance at all

proposed intersections, both internally and at the county road intersection, meet Appendix I, Section VI, B 12 and 13 of this Chapter.



D. Utility Easements: Easements of not less than seven and one-half (7-1/2) feet in width shall be provided on all property lines or right-of-way lines, where necessary for poles, wires, conduits, storm and sanitary sewer pipe, gas water, telephone, cable TV or other utilities.

E. Blocks: No block should be longer than one thousand three hundred twenty

(1,320) feet.

F. Lots:

(1) The lot arrangement and design shall be such that all lots will provide satisfactory and desirable building sites properly related to topography and the character of adjacent development.

(2) All side lot lines shall be substantially at right angles or radial to street

center lines unless the Planning and Zoning Commission shall agree that a variation to this requirement will provide for better street and lot arrangement. Double frontage lots shall be avoided except where essential to provide separation of residential development from major traffic arteries or to overcome specific disadvantages of topography.

(3) The minimum dimensions for lots shall be in accordance with the bulk

regulations of the Zoning Ordinance for the district within which the subdivision is located; provided, however, that the minimum depth for a lot shall be one hundred (100) feet and that the depth shall not exceed three (3) times the width, unless it is a flag lot.

(4) Flag lots are permitted if the stem is at least twenty (20) feet wide from

the street to the buildable portion of the lot.

(5) Corner lots shall be of such width as to permit the maintenance of all yard requirements as required by the Zoning Ordinance.

(6) All lots at street intersections shall have a radius of not less than twenty-

five (25) feet at the street corner. A greater radius shall be required for intersections involving one or more major streets. A cut-off or chord may be substituted for the circular arc.

G. Building Lines: Building lines shall be shown on all lots intended for

residential, commercial or industrial use. Such building lines shall not be less than the minimum yard requirements of the Zoning Ordinance for the district within which the property is located.

H. Sanitary Sewers: Subdivisions containing less than thirty (30) lots may install



septic systems or other approved on-site treatment systems using County Health Department standards. Subdivisions containing thirty (30) or more lots when median lot size is less than one (1) acre shall provide for common sanitary sewage treatment using the administration rules of the Iowa Department of Natural Resources. Subdivisions containing more than thirty (30) lots when 90% or more of the lots are greater than 1 acre in size may install septic system in lieu of the common treatment using County Health Department standards. Lots where septic systems are proposed shall provide adequate space for two (2) septic fields, the second field to act as a back up when the first field fails.

I. Storm Water Management: All lots and internal streets shall be adequately

drained. Storm water runoff shall be controlled through enclosed storm sewers or overland drainage. Detention facilities sufficient to capture the runoff of a one hundred (100) year storm shall be placed in the subdivision. The release rate of storm water out of the detention facility shall be restricted so as not to exceed the volume produced by a five (5) year storm when measured at the pre-developed flow rates. The velocity of the water leaving the subdivision shall be reduced so as not to cause erosion. Drainage easements or common outlots may be required, but the land shall remain privately owned. Suitable provisions for maintenance and upkeep of common stormwater facilities shall be provided through homeowners association, deed covenants, or through other similar provisions as approved by the Board of Supervisors. A drainage easement is required where storm water from a subdivision crosses an adjacent property to reach a natural stream or public drainage facility. Enclosed storm sewers require County Engineer approval before construction of the subdivision begins.

J. Water: Subdivisions containing fifteen (15) or more lots that are located

within ½ mile of a public water utility shall extend water service from such utility when determined to be feasible. Subdivisions containing five (5) or more lots shall provide for a common water supply using the administrative rules of the Iowa Department of Natural Resources. Subdivisions containing fewer than five (5) lots may have private wells which meet the County Health Department standards. Once the development is complete, the restrictive covenants will provide for the common water system to be turned over to a homeowners' association or quasi-public organization. The association or organization would own, operate, and maintain the common water system.

K. Character of Development: The Board of Supervisors shall have the right to

agree with the subdivider regarding the type and character of development that will be permitted in the subdivision, and may require that certain minimum regulations regarding this matter be incorporated in deed restrictions. Such regulations shall be intended to protect the character and



value of the surrounding development and shall also tend to secure the most appropriate development of the property being subdivided.

L. Easements Along Streams: Whenever any stream or major surface water

course is located in an area that is being subdivided, the subdivider shall, at his own expense, make adequate provisions for protecting the channel so that it will properly carry the surface water. If the stream or water course drains an area in excess of ten (10) square miles, an application shall be made directly to the Iowa Department of Natural Resources. For drainage areas less than ten (10) square miles, any changes in the stream or water course as a result of the subdivision shall be approved by the Board of Supervisors during the subdivision review process. The subdivider also shall provide and dedicate to the Board of Supervisors an easement along each side of the stream, such easement shall be for the purpose of widening, improving or protecting said streams. The width of such easement shall be adequate to provide for any necessary channel relocation and straightening, but in no case shall such easement be less than fifty (50) feet on either side of stream centerline.

M. Erosion and Sediment Control: Practical combinations of the following general

principles will provide effective erosion and sediment control when properly planned and supplied:

(1) The topography and soil characteristics will determine the type of

development so as to minimize the erosion potential.

(2) Grading or alteration of land within the one hundred (100) year flood plain of watercourses will not be permitted unless sufficient topographic and hydrologic data are presented to indicate that improvements will be sufficiently protected from flooding and that the alteration will have no detrimental effect on the flow characteristics of the stream.

(3) Permanent vegetation and improvements such as streets, storm sewers

or other features of the development, capable of carrying storm run-off in a safe manner, shall be scheduled for installation to the greatest extent possible before removing the vegetative cover from the area.

(4) Wherever feasible, natural vegetation shall be retained and protected.

(5) Where inadequate vegetation exists, temporary or permanent vegetation

shall be established.

(6) The smallest practical area of land shall be exposed at any one time during development.



(7) When land is exposed during development, the exposure shall be kept to the shortest practical period of time.

(8) Critical areas exposed during construction shall be protected with

temporary vegetation and/or mulching.

(9) Sediment basins (debris basins, desilting basins, or silt traps) shall be installed and maintained to remove sediment from run-off waters from land undergoing development.

(10) Provisions shall be made to effectively accommodate the increased run-

off caused by changed soil and surface conditions during and after construction.

(11) Topsoil shall be stockpiled and protected by temporary vegetation or

mulching and returned after grading and development is complete.

(12) The permanent final vegetation and structures shall be installed as soon as practical in the development.

(13) All measures undertaken to reduce erosion and control sediment shall be

in conformance with the official technical standards and specifications of the Scott County Soil Conservation District.

N. Protection of Natural Vegetation Cover: Whenever a wooded site is to be

developed no more than fifteen percent (15%) of the naturally occurring canopy-tree cover shall be removed due to surface earth grading, roadway construction, building site clearance, or any other construction activity associated with subdivision site improvement. Whenever removal of more than fifteen percent (15%) of the naturally occurring vegetation cover is deemed necessary and unavoidable a mitigation replanting measure shall be implemented. Such mitigation shall require re-establishment of one (1) native tree of a similar specie to those removed for every three trees of three (3) inch caliper or greater removed or fatally damaged. Environmentally sensitive and primitive areas should be avoided to the greatest extent possible. Such areas include slopes in excess of 25%, native forest growth, native prairie grass, and wetlands. If development is proposed for such an area, the subdivider shall present a protection plan to the Planning and Zoning Commission.

O. Open Space Requirements: In all residential subdivisions of fifteen (15) lots or

more there shall be a minimum area of ten thousand (10,000) square feet plus an additional two thousand (2,000) square feet for each lot over fifteen (15), dedicated or reserved as usable, common open space land. The land need not



be contiguous, but no parcel dedicated or reserved for common open space shall be less than ten thousand (10,000) square feet in size. Common open space land shall be clearly designated on the subdivision plan as to character of use and development, be intended for the private use of the residents of the subdivision, and shall not include:

i. Areas reserved for the exclusive use or benefit of an individual tenant or

owner;

ii. Dedicated streets, common wells, sewer treatment facilities, open drainage ditches, drainage storage areas, other public rights-of-way, and other areas deemed unsuitable open space;

iii. Vehicular drives, parking, loading, and storage areas.

(1) Suitable provisions for maintenance and upkeep of open space shall be provided through homeowners association, deed covenants, or through other similar provisions as approved by the Board of Supervisors.

(2) Large lot subdivisions, provided that at least ninety percent (90%) of all

lots have lot areas of 1-1/2 acres or more shall be exempted from the open space requirements of this provision provided that adequate deed restrictions shall limit subsequent lot re-subdivisions. Exemptions may be provided if close to an existing public park or for personal hardships.

(3) Additional guidelines for determining open space:

(a) May include environmentally sensitive land such as stream beds,

marshes, and steep slopes; however, a minimum of fifty percent (50%) of the land must be level ground that is contiguous and suitable for active recreation;

(b) The length is not more than five (5) times the width;

(c) Be easily accessible to all property owners within the subdivision;

(d) May include land in a high power transmission line easement, but

only a maximum of twenty percent (20%) of the open space requirement.

(4) Bikeways may be included in the designated open space, but follow

these construction standards:

(a) Right-of-way at least twelve (12) feet wide; and,



(b) A paved surface at least eight (8) feet wide, three (3) inches thick,

on a well drained subsoil base.

As an incentive, the lands designated for a bikeway shall count double towards fulfilling the minimum open space requirement, provided that at least ten thousand (10,000) square feet of other open space has been set aside for active and passive use. The bikeway need not comply with the guidelines of Section 9-17 (O) (3).

P. Perimeter Fences: Any subdivision boundary adjoining an existing

agricultural land use will be fenced with a lawful or a tight fence, as determined by the Board of Supervisors, to prevent livestock and horses from entering the other property. Where no fence exists or where an existing is in need of repair, the cost will be assigned to the developer. Future repair and maintenance will be done by the agricultural land owner with the cost prorated according to length of fence between the homeowners association and the agricultural land owner.

Q. Protecting Integrity of Drainage Tile: The subdivider shall design and

construct the subdivision to protect the integrity of existing draining tile. If an operating drainage tile is not discovered until construction has begun, work shall stop until a new layout for the drainage tile has been engineered which is acceptable to the affected agricultural land owner. Differences between the developer and agricultural land owner will be decided by the Board of Supervisors.

SEC. 9-18. IMPROVEMENTS OR BOND REQUIRED

Before the Final Plat of any area shall be approved by the Board of Supervisors and recorded, the subdivider shall make and install the improvements described in this section. In lieu of final completion of the minimum improvements required before the plat is finally approved, the subdivider shall post a completion obligation bond, a set-aside letter from the bank, or comparable financial commitment, approved by the County Attorney and County Treasurer, with the Board of Supervisors, which will ensure to the County that the improvements will be completed by the subdivider. A detailed engineering estimate of cost for all improvements shall be prepared by the subdivider's engineer and shall bear the seal of a registered professional engineer. This will be used by the County Engineer for review and determination of the bond amount. The amount of the bond shall not be less than the estimated cost of the improvements and the amount of the estimate must be approved by the County Engineer. If the improvements are not completed the County may use the bond or any portion thereof to complete same. For plats located in unincorporated areas within two (2) miles of the corporate limits of a municipality, the Planning and



Zoning Commission and Board of Supervisors may waive the requirements of this section provided they are satisfied that the subdivision regulations of the municipality governing the area within which the subdivision is located or the terms of a Chapter 28E agreement, if applicable, are sufficient to ensure adequate conformance with these regulations.

SEC. 9-19. REQUIRED IMPROVEMENTS

The minimum improvements installed or for which bond is posted in any subdivision, before a final plat is approved shall be based on the total number of lots in the proposed subdivision plus any additional lots anticipated for any of the remaining adjacent unplatted land. The following subsections shall apply:

A. All new subdivision streets which will eventually serve five (5) or more lots will

be constructed according to the standards and procedures as established by the Board of Supervisors. When the majority of the lots are sold to homeowners, the homeowners association may decide whether or not to dedicate the road and road right-of-way to the County. The roads will be constructed with an adequately compacted sub-soil base and proper drainage. The County Engineer will inspect and approve the sub-soil base and drainage before the base course is laid. The traffic surface will be built to the standards listed below and based on projected traffic counts for the subdivision as eventually completed. The paved portion shall meet standards equal to or greater than current Statewide Urban Design and Specifications (SUDAS) Manual and current Iowa Department of Transportation specifications.

(1) Local residential road standards (projected average daily traffic count

under 250 vehicle trips) will depend upon the storm water drainage system. Underground: Right-of-way - fifty (50) feet, street width - twenty-six (26) feet wide back-to-back including four (4) inch roll curb and gutter. Open ditch: Right-of-way – sixty (60) feet, street width twenty-two (22) feet wide with no curb; shoulders - four (4) feet wide. (See Appendix I to this Chapter for further details).

(2) Sub-collector road standards (projected average daily traffic count over

250 vehicle trips) will depend upon the storm water drainage systems. Underground: Right-of-way - fifty (50) feet; street width - thirty (30) feet wide back-to-back including four (4) inch roll curb and gutter. Open ditch: Right-of-way seventy (70) feet; street width twenty-four (24) feet wide with no curb; shoulders - four (4) feet wide. (See Appendix I to this Chapter for further details).

B. All new subdivision streets which are not projected to serve more than four (4)

lots shall be designed and constructed to provide year round access for



motorized vehicles. The County Engineer must approve the plans for the road, cross section, shoulders and ditches before road construction begins. In no case shall the traffic surface consist of less than six (6) inch coarse aggregate base with a two (2) inch fine aggregate surface with a dust retardant surface. The County Engineer may require a soil test of the sub-soil along the planned road bed. The right-of-way width will be fifty (50) feet minimum. Two (2) foot shoulders will be constructed on either side of the traffic surface.

C. The subdivider shall construct sanitary and storm water sewers according to

the standards and specifications of Sections 9-17 (H), 9-17 (I), and Appendix I to this Chapter and the Iowa Department of Natural Resources regulations and provide a sanitary sewer connection to each lot. Health Department regulations do not permit installation of septic tanks on lots less than fifteen thousand (15,000) square feet in area. Where permitted, the subdivider shall furnish reports from the County Health Department and the engineer testing the lots, stating that the proposed lots have been tested and found suitable for primary sewage treatment. Approval from the Iowa Department of Natural Resources is required for a common water supply or sewage treatment system serving fifteen (15) or more dwelling units or twenty-five (25) or more persons. The County Health Department must approve a water supply or sewage treatment system serving fewer units or people.

D. Permanent monuments shall be set in each corner of the perimeter of the

subdivision and at the corner of each block within the subdivision and at the corner of each lot, in accordance with Chapter 409A, Code of Iowa. All monuments shall be made of permanent material, sensitive to a dip needle and at least thirty (30) inches long, and shall conform with standard specifications of the County Engineer.

E. The subdivider will provide the water mains and lines in accordance with the

provisions of this Chapter and other State and County regulations.

(1) No water mains or lines of the central water-tight system or sewer lines, except a stub end from said lines, shall be installed underneath the normal traveled portion of any street. The same to be located in an appropriate place as approved by the County Engineer.

(2) No street shall be maintained by Scott County unless and until a

workable agreement has been entered into between the Board of Supervisors and the subdivider which will appropriately set forth the responsibility for payment of all costs by the subdivider or persons acquiring land therein for the maintenance of water and sewer utilities installed in accordance with this Chapter; and further providing for payment to the County for any damage caused to roads which may occur



by reason of maintenance of water and sewer lines.

F. All internal traffic control signs shall be placed by the developer in accordance with the Iowa Manual of Uniform Traffic Control Devices as part of the road and street construction; i.e., regulatory, warning, etc.

G. The Board of Supervisors and Planning and Zoning Commission may require

that all utility lines except electric lines of nominal voltage in excess of 15,000 volts, be installed underground. The subdivider shall be responsible for making the necessary arrangements with the utility companies for installation of such facilities. Said facility lines shall be installed in such a manner so as not to interfere with other underground utilities. The location of all utilities within the road and street R.O.W. shall be approved by the County Engineer and shown on the engineering plans. Underground utility lines which cross underneath the right-of-way of any street, or way shall be installed prior to the improvements of any such street, or way in the subdivision. Incidental appurtenances, such as transformers and their enclosures, pedestal mounted terminal boxes, meters and meter cabinets may be placed above ground but shall be located so as not to be unsightly or hazardous to the public. If overhead utility lines or wires are permitted, the electrical utility shall have the right to determine overhead line routing. In their determination on whether or not to require underground utilities, the Board of Supervisors and Planning and Zoning Commission may consider the recommendations of the utility company on such matters as soil, topography, or other conditions which make most installations within the subdivision unreasonable or impractical.

H. The subdivider shall provide an acceptable trust agreement or covenant within

the deed restriction for adequate continuous maintenance of the subdivision roads, street signs, entry structures (if applicable), parks, sanitary and storm sewers, water supply system, and common facilities by the lot owners of the subdivision.

I. All plans, specifications, installation and construction required by this Chapter

shall be subject to review, approval and inspection in accordance with Appendix I of this Chapter by the County Engineer or his authorized representative.

(1) The County may require contracts for all public improvements to be

executed on forms furnished and approved by the County Attorney and the Board of Supervisors.

(2) The subdivider shall furnish the County Engineer with a construction

schedule prior to commencement of any and/or all construction, and shall notify the County Engineer, not less than forty-eight (48) hours in



advance of readiness for required inspection. The subdivider shall reimburse the County for the costs expended for all inspection services and tests furnished and conducted by or on behalf of the County.

(3) The subdivider shall pay the County Engineer's office the standard rate

for reviewing plans and specifications, inspecting and testing new roads and storm sewer systems, and any additional costs directly associated with installing the subdivision improvements.

J. The subdivider shall be responsible for the installation and/or construction of

all improvements required by this Chapter, and shall warrant the design, materials and workmanship of such improvements' installation and construction for a period of two (2) years from and after completion. Such warranty shall be by bond or other acceptable collateral; and shall be subject to review by the County Attorney; shall assure the expedient repair or replacement of defective improvements under warranty; and shall indemnify the County from all costs or losses resulting from or contributed to such defective improvements.

SEC. 9-20. VARIATIONS AND EXCEPTIONS PERMITTED

Whenever the tract proposed to be subdivided is of such unusual size or shape or is surrounded by such development or unusual conditions that the strict application of the requirements contained in this Chapter would result in substantial hardships or injustices, the Board of Supervisors upon recommendation of the Planning and Zoning Commission may modify or vary such requirements to the end that the subdivider is allowed to develop the property in a reasonable manner; provided, however, that all such variations and exceptions granted hereunder shall be in harmony with the intended spirit of this Chapter and granted with the view toward protecting the public interest and welfare. Any variance recommended by the Planning and Zoning Commission is required to be entered in writing in the minutes of the Planning and Zoning Commission and the reasoning on which the departure was justified shall be set forth.

SEC. 9-21. LIMITATIONS

In no case shall any street standard variation or modification be more than a minimum easing of the requirements. In no case shall it have the effect of reducing the traffic capacity of any street or be in conflict with the Zoning Ordinance and Map.



SEC. 9-22. APPROVAL REQUIRED

Such variances and waivers may be granted by the affirmative vote of three-fifths (3/5) of the members of the Board of Supervisors.

SEC. 9-23. CONDITIONAL APPROVAL

In granting variances and modifications, the Board of Supervisors may require such conditions as will, in its judgment, secure substantially the objectives of the requirements so varied or modified.

SEC. 9-24. AMENDMENTS

Any regulation or provision of this Chapter may be changed and amended from time to time by the Board of Supervisors; provided however, that such changes and amendments shall not become effective until after study and report by the Planning and Zoning Commission and until after a public hearing has been held, a public notice of which shall have been given in the official newspapers in compliance with State law.

SEC. 9-25. ENFORCEMENT

No plat of any subdivision shall be entitled to be recorded in the County Recorder's office or have validity until it shall have been approved in the manner prescribed herein.

The Director shall not issue building permits or certificates of occupancy for any structure located in any subdivision, the plat of which has been prepared after November 15, 1979, but which has not been approved in accordance with the provisions contained herein.

SEC. 9-26. MUNICIPAL INFRACTION

Whoever, being the owner or agent of the owner of any land located within the unincorporated area of Scott County, knowingly or with intent to defraud, transfers or sells by reference to or exhibition of or by other use of a plat of subdivision of such land before such plat has been approved by the Board of Supervisors, shall be liable for the penalties outlined in the municipal infraction Chapter 29 of the County Code.

Streets should be arranged to provide for a continuous circuit for travel and provide for two access points whenever possible; the right is reserved to reject "dead-end" streets or roads. The preliminary plat shall be subject to all the requirements of Section 9-17 of the Code and any other engineering criteria deemed appropriate and applicable.

The purpose of the preliminary plat is to provide for a review of the geometrics and general layout, safety of access points to county roads, the suitability and practicality of the proposed development, the compatibility with the surrounding area, the existence of any special topographical and/or soil problems, the need for any special design and plan requirements and other items affecting the development of the final plat.

A. The following minimum widths of right-of-way will be required:

1. Internal drainage easements along lot lines is twenty (20) feet

minimum.

2. Natural drains of ten (10) square miles or more drainage area is fifty (50) feet minimum.



3. Local residential streets:

Curb and gutter - fifty (50) feet Open ditch - sixty (60) feet

4. Sub-Collector Streets:

Curb and gutter - fifty (50) feet. Open ditch - seventy (70) feet.

5. Private streets serving four (4) lots or less:

Open ditch - fifty (50) feet

6. Existing County roads: Local area service roads - sixty-six (66) feet. Farm to market roads - one hundred (100) feet. Federal and Secondary roads - one hundred twenty (120) feet.

Note: Platting along County roads on one side would require one half (1/2) of the above.

Note: Greater widths of right-of-way may be required when considered necessary for heavier or higher traffic counts.

B. The following minimum pavement thickness will be required for public

roads:
